[U-Boot] [PATCH 1/2 v2] FSL/eSDHC: enable the peripheral clock to detect the card
From: Jerry Huang Chang-Ming.Huang@freescale.com
According to the card detection of p1/p2 platform RM, we should set SYSCTL[PEREN] to enable the clock. Otherwise, after booting the u-boot, and then inserting the SD card, the SD card can't be detected.

Hi, Do you have any comment about this patch? It can be merged into next version?
Best Regards Jerry Huang
